Question
An organic compound ‘X’ on heating with cone. $\text{H}_{2}\text{SO}_{4}$ forms a compound ‘Y’ which on addition of one molecule of hydrogen in the presence of nickel forms a compound ‘Z’. One molecule of compound ‘Z’ on combustion forms two molecules $\text{CO}_{2}$ of and three molecules of $\text{H}_{2}\text{O.}$ Identify giving reasons the compounds ‘X’, ‘Y’ and ‘Z’. Write the chemical equations for all the chemical reactions involved.
